SUPPORT.

Specification of Letters Patent.

Patented Oct. 8,1918.

Application filed November 21, 1917. Serial No. 203,167.

To all whom it may concern:

Be it known that I, NORMAN C. NIooL, a citizen of the United States of America, residing in Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Supports, of which the following is a specification.

This invention relates to supports for parts separable from one another, such as boxes, trunks, casings, etc., provided with lids or covers, or the like, and aims to provide improvements therein, and is an improvement for certain purposes on the construction shown in my application for Letters Patent of the United States, filed May 26, 1915, Serial No. 30,523.

In my said application there is disclosed a device or means, whereby .the supporting elements, when the lid or cover is raised, will automatically lock the same in such position, and by a further movement of the lid or cover the lock will be released and prevented from ree'ngaging while the lid .movement between the prop and lock, or

wherein the guardpartakes of a substantially less amount of movement. The present invention is especially directed to that part of the broad idea of invention wherein the guard has but limited movement on the prop. This. construction 1s of especial importance and advantage in connection with supports of plated or polished metal wherein wearing ofi or scratching of the surfaces of the metal, by reason of extensive movement of the guard on the prop,

Figure 1 illustrates a vertical cross-section of a box having the invention applied thereto; l

Fig. 2 is an enlarged detail view of the position of the parts 7 Figs. 35 inclusive, .are views similar to Fig. 2, illustrating the prop and guard in different operative positions, and

Figs. 6 and 7 are detail views of the guard.

In said drawings, wherein the support is illustrated as applied to a box, numeral 1 designates a box, 2 its cover, and 3 the support. Numeral 4 designates the prop, and 5 the guard. The guard is provided with an irregular opening 13 therein, and is fitted upon the prop in such manner that it may slide thereon with slight friction, to this end being conveniently provided with curled edge portions 16 fitting around the edges of the prop. See Figs. 6 and 7. The prop is attached to the cover, as by the pin or screw 6 passing through a hole in the prop and fastening into the cover.

7 designates a locking pin fixed upon the box. This locking pin 7 passes through a slot 8 provided in the prop, and is adapted to fit within a recess 9 for holding the cover and box in open or separated position.

When the cover is lifted the locking pin 7 slides in the slot 8 in the prop until it strikes a projection 10. This pro ection 10 forcesthe locking pin 7 to assume a position against a part of the wall 11 of the recess 9. jection 12, between which projection 12 and the wall 11 the locking pin 7 becomes jammedor stopped.- This prevents further opening movement of the .cover 2. By simply dropping or lowering the cover after the openlng movement has been arrested, as just described, the lockingpin 7 falls within the recess 9, as indicated in Fig. 4, and the cover is thereby securely supported.

The guard 5 has a part 14 (Fig. 3) which The guard 5 has thereon a prostrikes against the pin 7 as the pin enters the recess 9, which contact with the pin 9 causes the guard to be slid to a slight extent upon the prop, thereby raising the projection -l2 on the prop to a position (Fig.

4) where the locking pin 7 will pass between said projection and the wall part 11 of the recess.

To move the cover on the box to closed position, the support beingin the position shown in Fig. 4, the cover is lifted, the lock ing pin 7 passingfinto the recess 15 at the the guard has been raised to a position which permits the locking pin 7 to pass between said projection 12 and the projection 11 on the prop. I

When the locking pin 7 strikes the wall 17 of the lower part of the opening 13 in the guard, the guard is slid upon the prQP until the pin 7 comes in contact with the wall 18 at the lower side of the recess 15 in the prop. The parts will now be in the position shown in Fig, 5. When the guard is slid to its lowermost position, a part 1-9 is moved into position to cover the entrance to the locking recess 9.

YVhen the cover is now moved to closing position, the pin 7 passes around the projection 12 upon the guard, and the projection 10 upon the prop and is prevented from entering the locking recess by the part '19 of the guard. Thep'in then comes in -'contact with a shoulder 20 upon the guard, and during a succeeding part of the closing movement of the lid the guard 5 is slid upon the prop. The slot 8 has a curved wall'22, somewhat above the locking recess 9, and this curved wall of the slot 8 acts to move the prop relatii' e1y to the pin 7 in such manner that the pin moves from behind the shoulder 20 upon the guard, When the pin 7 moves from behind the shoulder 20, the pin '7 is free to move in the slot 8 without carrying with it the guard 5. The relative position or the parts at this stage of jthe closing of the cover is shown in Fig.9. The movement of the guard by the action of the pin 7 against the shoulder 20 I at the same time "carries the part 19 out of position to obstruct the entrance to the locking recess 9 and brings the 'projection12 of the guard in position to cooperate with the part '10 of the prop in throwing the prop in such manner that whenthecover is again lifted the pin strikes the projecting part 11 upon the prop, and becomes held thereagainst by the coiiperation of the projection 12 upon the guard.

The operatienof the device will be understood from the foregoing description.

. It will be seen that the movement of the guard '5 upon the prop 4 is, or can be made to be, .very slight, in such manner that scratching or wearing of a plated o'r polished prop, except a small portion near its end, 1s avoided.

Moreover, it will be seen that the separable part, as the cover, is definitely stopped at a position where the locking pin '7 is adjacent the locking recess, and certainly falls within the locking recess when the lid is released. zlhereupon the cover may "be closed by simply lifting the cover slightly and closing it, the locking recess being obstructed such manner that {no care of manipulation is necessary in order "to ;pre-

vent the locking pin entering the locking the subject of the invention may be applied to separable parts generally.

What I claim is; a

1. A support for separable parts such as a-box and its cover,- comprising a prop and a guard, and a locking pin, said guard being slidable longitudinally of said prop and being considerably shorter than said prop, said pin being movable beyond said guard, said prop having a locking recess, said guard having a -part adapted to cover and uncover said locking recess and being moved by said pin, and-means for disengaging saidpin and guard, whereby said guard has but limited movenient with respect to said prop.
